Title: Semiconductor device
Inventor: KONDOU HISAO
IPC: H01L23/58
Filed: 1980-04-10
Abstract: PURPOSE:To prevent thermal runawoy and to keep the saturation voltage of the  collector and emitter low by making a resistance layer which has negative temperature dependence on a surface-insulated film of an Si substrate in such a manner as  to be connected to a base and emitter layer and covered therwith. CONSTITUTION:The resistance layer 4 of a p type Si is provided on an SiO2 film 10 connected to electrodes 1 and 2 of a base 7 and an emitter 3. Doping quantity for the poly Si is selected to control the resistance value and the temperature coefficient negative. When Al is used for the electrodes, the use of p type impurities facilitates the ohmic contact. To detect the junction temperature accurately, the resistance layer 4 is made across the emitter 3 and the base 7. In addition, when provided entirely covering SiO2 10, the resistance layer 4 can ease the accumulation of electric charge on the film 10 while there is no increase in the leak from the collector and base junction. This prevents thermal runawoy while lowering the saturation voltage  of the collector and emitter. Thus, a device can be obtained with limited characteristic variation due to the accumulation of electrical charge.

Title: Optical fiber type polarization plane rotating element
Inventor: MIYOUGADANI TOORU
IPC: G02B6/00
Filed: 1986-03-06
Abstract: PURPOSE:To simplify the constitution of a rotating element greatly and to reduce its size and weight by drawing a twisted part of an optical fiber linearly for looping and controlling the rotation of a plane of polarization. CONSTITUTION:A point O of the single-mode optical fiber is fixed and a point B is twisted by one turn to form one loop, so that the point B rotates by 360 deg. from the plane of polarization in the twisting direction. On the other hand, when the point O is fixed and the part between the points O and B is twisted by one turn, the plane of polarization of propagated light rotates by about 25 deg. at the point B. Consequently, when light is propagated from the point O to the point B, the fiber is looped and drawn and the point B is shifted in position properly to adjust the angle of the plane of polarization at the point B by 0-35 deg.. Consequently, the fiber part between the points O and B is usable as a polarization plane rotating element and the constitution of the element can be simplified greatly, so that the element is reduced in size and weight.

Title: Seal device for movable wing variable axial flow fan
Inventor: YOKOYAMA EIJI
IPC: F04D29/36
Filed: 1982-03-29
Abstract: PURPOSE:To make it possible to prevent without fail the invasion of dust, etc., by equalizing the amount of gas blown off from a gap between a wing mounting hole and a mavable wing shaft along the periphery of the movable wing shaft while providing a narrow part in said gap. CONSTITUTION:A seal device is constructed so as not to provide a uneven gap 6 even if a movable wing 1 is excentric against a wing mounting hole 2a. The width of the gap 6 is narrow near the external peripheral surface of a boss 2, thus offering a sufficient gas blow-off velocity. The radial dimension of the narrow cornering part 7 is limited to the minimum, so that said width over the most part of the gap 6 is sufficiently large. Accordingly, even if the movable wing shaft 1 is excentric against the wing mounting hole 2a, gas is always blown off uniformly along the periphery, thus preventing the invasion of dust.
